Embodiment 1

[0026] A device for producing biodiesel from swill oil, including an agitator and a feeding device, the agitator 8 is installed in the center of the cover plate and controlled by a motor, and is characterized in that it includes a conical reaction kettle body, and the reaction kettle 1 is There is a cover plate; the reaction kettle 1 is provided with an electric heating rod 2, and the upper end of the electric heating rod 2 is fixed on the cover plate; there are eight electric heating rods 2 in the reaction kettle 1, which are evenly fixed on the cover plate, so that the reactants can be evenly Heated, to prevent local heating bumping phenomenon.

[0027] The reactor 1 is also provided with an electrostatic magnetic field positive pole 3 and an electrostatic magnetic field negative pole 4 fixed on the cover plate. The use of the electrostatic magnetic field pole can accelerate the sedimentation of the substance during the static reaction process and is beneficial to the separat...

Embodiment 2

[0036] The method utilizing the device of embodiment 1 to prepare biodiesel with swill oil may further comprise the steps:

[0037] The kitchen swill oil separated from the food waste is pumped into the reaction kettle 1 from the raw material feeding pipe 7, heated by eight electric heating rods 2, stirred by the stirrer 8 to 90 degrees, and then left to stand, and the static magnetic field positive rod 3 and The electrostatic magnetic field negative rod 4 works to force the debris and moisture in the kitchen swill oil to settle quickly, and then the sediment and water are discharged from the discharge port 14 of the electromagnetic valve at the bottom of the reaction kettle.

[0038] 100 kg of kitchen swill oil pretreated in the reaction kettle is heated to 70 degrees by eight electric heating rods 2, fully stirred by the stirrer 8, and the acid catalyst feeding tank 6 is fed into the 2 1 kilogram of acid catalyst and add 30 kilograms of methanol through the methanol electrom...

Abstract

The invention discloses a device for producing bio-diesel by using swill oil and a preparation method for the bio-diesel, which are characterized in that the device comprises a conical reaction kettle. The reaction kettle is provided with a cover plate, an electric heating rod is arranged in the reaction kettle, the upper end of the electric heating rod is fixed on the cover plate, and a static magnetic field anode rod and a static magnetic field cathode rod which are fixed on the cover plate are further arranged in the reaction kettle. A feeding device comprises an acid catalyst feeding tank, a raw material feeding pipe, a methanol feeding tank and an alkali catalyst feeding tank, the feeding device is arranged on the cover plate, and a discharging port is arranged in the middle of the bottom. The preparation method of the bio-diesel includes that the bio-diesel is obtained through reaction of the swill oil and methanol in the presence of catalyst. The device for producing the bio-diesel by using the swill oil is simple in structure and utilizes stirring and action of the static magnetic field rods to produce the bio-diesel. Raw materials are easy to obtain, production processes are simple, production devices are closed fully, and secondary environment pollution cannot be caused. The device producing the bio-diesel by using the swill and the preparation method for the bio-diesel effectively solve the problem of resource recycling of the swill oil in kitchen waste, thereby achieving the purpose of making kitchen waste profitable, and simultaneously improving food safety.

Description

technical field [0001] The invention relates to kitchen waste treatment equipment, in particular to a device for producing biodiesel from swill oil and a preparation method thereof. Background technique [0002] Using kitchen swill oil as raw material to produce biodiesel is a new technology developed in line with environmental protection requirements, and it is a new renewable green energy source. At present, domestic biodiesel production is still dominated by chemical methods, using animal and vegetable oils as raw materials, through catalysis and transesterification to generate biodiesel. In the production process, it is difficult to control the addition of excess methanol or ethanol in the presence of catalyst acid or base, which is recovered and recycled. These processes are mature, but the cost of raw materials is relatively high, so the cost of biodiesel is inevitably limited. Contents of the invention [0003] The technical problem to be solved by the present inv...
